COVID-19: Severe crackdown on Covidiots, massive scale-up in vaccination run-rate needed to contain second wave

Mass masking up, strict enforcement of COVID-19 protocols are the clearest ways to contain the spread. Otherwise, the cost for lives and livelihoods will be too prohibitive for the country to bear.

As of March 29, 2021 evening, there were 12,095,855 reported COVID-19 positive cases in India, accounting for about 9.4 percent of the world’s 128 million cases.

In March 2020, when the virus started to rapidly engulf the country’s landscape, the government had to make a hard trade-off of choosing between lives and livelihood. It chose the former, imposing one of the most stringent lockdowns, a standard, and perhaps the only, tool that embattled governments had at the time.

Curative medicines, let alone vaccines, were still a very distant certainty, as epidemiologists, scientists and biostatisticians rummaged through the mountains of data in mankind’s battle against the virus. The Indian government, much like most others, deployed the lockdown to slow down the virus’ spread.

In September 2020, when the first wave of COVID-19 infections peaked in India during the first wave, the seven-day daily moving average of daily infections in the country was more than 96,000.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
